EtherWAN has developed a line of Ethernet extenders that can provide Ethernet connectivity over existing coaxial or telephone/communication cables, regardless of the type of cable or wire used. The ED3501 and ED3541 Ethernet extenders are specifically designed to work with twisted and straight cables...
This type of network cable offers an ability to transmit signals over longer distances. It also provides the ability to carry information at faster space. Two types of fiber-optic cables are: Single-mode fiber (SMF)–This type of fiber optic cable uses only a single ray of light to carry...
Just buy a normal Ethernet RJ45 8-wire pass-thru adapter (about $2 from Fry’s Electronics), pop it open, and swap wires numbered 1 with 3 and 2 with 6. The result is a crossover ethernet adapter. If you have a two-Wire telephone (old-school) and wish to get it working, you ...
Over the years, computers have become ubiquitous, and many people use multiple devices at their jobs, including their laptops, smartphones, and tablets. Every VoIP telephone and every printer is a computer, and even building management systems and access controls (door locks) are networked. ...
The traffic then tunnels through an L2VPN over the SP core network to another edge router. The edge router sends the traffic down another attachment circuit (AC) to the customer's remote site. On the router, an AC is an interface that is...
